Introduction of waterproof micro switch related knowledge

The waterproof micro switch is a waterproof switch with a small contact distance and a snap-action mechanism, which switches with a specified stroke and a specified force. It is covered by a housing with a drive lever on the outside. Yes: In the waterproof micro switch type, the function of the switch is realized by the mechanical switch of the contact, compared with the semiconductor switch with the characteristics of the waterproof micro switch. working principle: The external mechanical force acts on the action reed through transmission elements (press pins, buttons, levers, rollers, etc.), when the action reed moves to the critical point, an instantaneous action occurs, making the moving and fixed contacts at the end of the action reed. Quick on or off. When the acting force on the transmission element is eliminated, the acting reed generates a reverse force, and when the reverse stroke of the transmission element reaches the critical point of the action of the reed, the reverse action is completed instantly. The micro switch has the advantages of small contact distance, short stroke, small pressing force and fast switching. The moving speed of the moving contact has nothing to do with the moving speed of the transmission element. Important parameters: 1. Anti-leakage index. Insert two electrodes into the sample, drop 50 drops of the prescribed solution (ammonium chloride 0.1[%]) between the electrodes without short-circuiting, which is the maximum withstand voltage value, and there are five grades. 2. Operation times: refers to the opening and closing times of the durability test specified in the specification. Each manufacturer selects the time from the table below, indicated by the symbol on the switch. In the IEC specification, the switching standard for high-frequency operation is 50,000 times, and the switching standard for low-frequency operation is 10,000 times. 3. Working ambient temperature: the temperature range that the switch can use. Application areas: Waterproof micro switches are widely used in various cold, humid, dusty and harsh environments. Such as automobiles, spraying equipment, etc.
